Mott-Hubbard transition in infinite dimensions
Ning-Hua Tong, Shun-Qing Shen, Fu-Cho Pu
We analyze the unanalytical structure of metal-insulator transition (MIT) in infinite dimensions. By introducing a simple transformation into the dynamical mean-field equation of H…
Two Magnetic Impurities with Arbitrary Spins in Open Boundary t-J Model
Zhan-Ning Hu, Fu-Cho Pu
From the open boundary t-J model, an impurity model is constructed in which magnetic impurities of arbitrary spins are coupled to the edges of the strongly correlated electron syst…
Enhancement of pair correlation in a one-dimensional hybridization model
Yupeng Wang, Jian-Hui Dai, Fu-Cho Pu +1
We propose an integrable model of one-dimensional (1D) interacting electrons coupled with the local orbitals arrayed periodically in the chain. Since the local orbitals are introdu…
Integrable impurities in Hubbard chain with the open boundary condition
Zhan-Ning Hu, Fu-Cho Pu
The Kondo problem of two impurities in 1D strongly correlated electron system within the framework of the open boundary Hubbard chain is solved and the impurities, coupled to the e…
Periodic Instanton and Phase Transition in Quantum Tunneling of Spin Systems
Y. -B. Zhang, Y. -H. Nie, S. -P. Kou +3
The quantum-classical transitions of the escape rates in a uniaxial spin model relevant to the molecular magnet MnAc and a biaxial anisotropic ferromagnetic particle are inv…
Pinning of slidding collective charge state in a 1D attractive fermion system
Shu Chen, Yupeng Wang, Fan Yang +1
We investigate an interacting fermion model with boundary potential by using Bethe ansatz method. The ground state properties of the system and the boundary effect are discussed. I…
